Voltage divider formula (with unknown R out and known R L) will give you Need ac only!) and measure the output voltage drop due to the load. Output impedance, load the output with a resistor R L (through a capacitor – you The voltage displaying the difference between the two channels. You may use the scope probes on the two ends of the resistor and measure The resistor should be large enough to measure the ac voltage across
MEASURE VOLTAGE GAIN IN MULTISIM 14.1 SERIES
Impedance, connect a series resistor to the input and measure voltage across Measure also input and output impedances (R in and R out). Parameters: small signal voltage gain, quiescent current, and the frequencyįor accuracy but note the phase relation between input and output waveforms Signal (output should not exceed 1 V) and measure the values of the design Wire the amplifier circuit following your design. Using the same signals as you will use in the laboratory. May deviate from the design specification by 10% if you do not find the requiredĬheck your design by simulating circuit performance with Multisim Obtain components from other sources, if needed. Specify component values to meet these requirements but check also the parts
The following conditions should be established: This is achieved byĪ proper resistor network. Must be properly biased and operate in the active mode. To work properly in an amplifier circuit a bipolar junction transistor (BJT) With Multisim and comparison with measured values.
